Hey, I am considering a breast augmentation procedure in Toronto. My friend has done her implant (cohesive silicone gel implant) surgery in a clinic in Toronto and her surgeon was Dr. Michael Kreidstein. She is happy with the result as it looks so real. What is the difference between cohesive silicone gel and saline implants? Which one is cost effective? I browsed through the internet and could not come to a conclusion. Anyone who has done this surgery, kindly share your experience.
